	"Catch Me If You Can" (CaMiCatzee) is a multimedia interlinking concept demonstrator. Our main goal is to show how multimedia assets (in our case still images) can be <a href="http://linkeddata.org/">interlinked</a> on the Web of Data.
	We envision to extend the <a href="http://sw-app.org/pub/eswc08-irs-poster.pdf">User Contributed Interlinking</a> (UCI) to multimedia assets. Clearly, the advantage is having high-quality semantic links
  from a multimedia asset to other data, hence allowing to connect to the linked datasets.

  <p style="padding:0px 200px 20px 200px; text-align:justify;">
  In <a href="http://flickr.com">flickr</a> it is possible to annotate parts of a picture using so called "notes" (see also <a href="http://www.flickr.com/services/api/">flickr's API</a>).
  As the primary domain, we chose people depictions of people. Typically, flickr notes contain a string stating, e.g., "person X is depicted in this picture". However, there is no
  straight-forward way to relate this information with other data, such as <a href="http://xmlns.com/foaf/spec/">FOAF</a> data, locations, and contextual information (conference, holiday, etc.). 
  This is where CaMiCatzee steps in: we apply the UCI principle by harnessing the fine-grained annotation capabilities of flickr in order to let people semantically annotate pictures.

  <p style="padding:0px 200px 20px 200px; text-align:justify;">
  But CaMiCatzee offers more than pure interlinking: In the "full report", the flickr tags of a picture are evaluated and used as a base for introducing rdfs:seeAlso links.
  This overview report is offered in <a href="http://www.w3.org/TR/xhtml-rdfa-primer/">XHTML+RDFa</a> allowing consumption by both humans and machines.

  This demonstrator is powered by <a href="http://www.foaf-project.org">FOAF</a>, <a href="http://arc.semsol.org">ARC2</a>, and <a href="http://sindice.com">sindice</a> semantic indexer;
  we would like to thank the people involved in building these technologies.
